Oil Cooler x Thermo Fan – Day 6

I was made aware this morning that the orientation of my oil cooler core was incorrect. Having both inlet/outlet located on the bottom causes air pockets to occur, and also very ineffecient cooling. The ideal way to mount the cooler core is to have it vertical with inlet at the bottom and outlet at the top. As oil enters the bottom and fills up the core, air is pushed out of the system.

So spent most of the morning making new brackets to re-mount the cooler core. Fortunately I didn't have to make any new braided hose, the existing ones were the correct lengths =)

New brackets made up.

All mounted up for a test fitting.

Also spent the morning prepping the relay/box. Two factory relays were removed and the rest were re-arranged to make some room for the new relays. All wires that won't be used were heat-shrinked and tucked away. Wires that are to be used were tagged for tomorrow.

Also finished up the Defi sensor wires and tidied it all up. You can also see the extra wire I ran for the fan controller temp sensor.
